Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
nhieu tang » chieu sang, hieu lang, nhiet nang
trung tuan » trung thanh, trung tam, tran tuan
trung cua » truong cua, trung cap, dung cua
ho nhieu » hop nhieu, ho chieu, he nhieu
van tuan » van quan, anh tuan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ho nhieu tang - thanh ((trung cua) OR (trung tuan)) thuong cong ((van tuan) OR (van ban)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho nhieu tang - thanh ((trung cua) or (trung tuan)) thuong cong ((van tuan) OR (van ban)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho nhieu tang - thanh ((trung cua) or (trung tuan)) thuong cong ((van tuan) OR (van ban)) cau*.
